When you find yourself trying to remember a show (or any works) that's on the tip of your tongue but just out of reach, come here - the collective brain of the TVTropes community can probably help. Post all the details you can remember (examples help). If you're looking for a trope, head over to Trope Finder. Have general questions about tropes? Visit Ask The Tropers!
This sounds very similar to Saya no Uta, which I think is a visual novel. The details don't exactly match though, but that may be because you weren't aware of all the story at the time? There's basically a guy who has an accident that makes him see the world as disgusting. There's also a girl, who turns out to be an alien. She eats people, and to everyone she looks like a disgusting monster, except to the guy. Something happens and she starts going to his house/living there. He doesn't know she's a monster yet. One day he walks in on her eating a human, and finds out. But he actually ends up joining her.
Idk if it is this, I want to check it out, but they only have pc and android downloads. Do you know any links to where I can view it on a macbook pro? (apple) I'm not totally sure if this is what I was looking for but I hope so :/ Im pretty sure it wasnt a playable novel, it was either some sort of anime or movie/film :/
Edited by TaeminnieWhat about watching a play-through on youtube? Here's Part 1: https://www.youtube.com/watch?v=tDHJ05TbDxU
. Although there seems to be a lot of reading, so it may not be what you were looking for then. The plot seems very similar to your description though, that's a shame.
It's not animated, and some of the details are different, but it reminds me a bit of Braindead/Dead Alive.
Edit: I missed the part about the girlfriend being the zombie. This probably isn't Braindead then.
Edited by supergod For we shall slay evil with logic...I'm not sure about the actual post content, but from the title alone, my first hunch would have been Let the Right One In (or its remake, Let Me In).

A while ago, I was in an anime phase, though I'm not sure if this movie/short film/series was animation or actual people. Here goes: All I can remember about this film is that there was a girl, she was some sort of zombie or vampire, but basically she ate people. I know that there was a Caucasian male who lived in a sort of run down apartment. I think he met this girl one day somewhere. They liked each other and had relations (i think). after that all I can remember is that one day, the guy came home from work, and he saw her eating a guy (it could have been the pizza guy or lanlord?) There was blood everywhere and he was freaking out that she was eating a person. He started yelling at her and stuff. Then he put he eaten body in a bag or something and put that bag in his bathroom? Life continued like this for a while until they had no where to put the bodies. I think he got arrested in the end, idk. The movie-thing had a generally dark theme to it. A very gloomy, dark colour scheme. IDKK tysm for helping <3
[EDIT]: This is solved, the movie was Bitten (2008) !
